provide that the obligations


                                       7

from such Sublicenses any terms that are not relevant to the Products so long as

royalties payable on such Products thereunder, remain comprehensible. In the
event that the terms of a Third Party agreement prevent Spectrum from providing
a copy of Spectrum's Sublicense with the Third Party, Spectrum shall provide a
summary in sufficient detail to enable Chicago Labs to calculate and verify the
royalties payable to Chicago Labs with respect to such Sublicense.

teaching and research activities, the results of which shall not be used for any
commercial purpose without the prior consent of Chicago Labs. Chicago Labs shall
not grant such consent to University without the prior written consent of
Spectrum which shall not be unreasonably withheld, provided that it shall not be
considered unreasonable for Spectrum to withhold its consent if the commercial
purpose might compete with the Products or any products that Spectrum develops
or markets, directly or indirectly.

             4.5.6 Royalty Offsets. In the event that royalty payments are owed
by Spectrum to Third Parties with respect to licenses necessary to use, develop,
manufacture or sell a Product and such royalty payments exceed *** percent
(***%) of Net Sales, the royalties owed to Chicago Labs under Section 4.5.1
shall be reduced by the amount of the royalty payments actually paid by Spectrum
to such Third Parties provided that such reductions shall not exceed *** of the
royalties due Chicago Labs under such Section in such country for the reporting
period. ***

             4.5.7 Sublicense Income. In case Spectrum grants sublicenses under
Section 3.2 hereof, Spectrum shall pay to Chicago Labs (A) if before ***, ***
percent (***%) or (B) if after ***, *** percent (***%), of any lump sum,

upfront fees, sublicense fees, or other consideration paid for the authorization
to use the Chicago Labs Technology to develop, make, have made, use, offer for
sale, sell, have sold, distribute, import, and export Products in the Licensed
Field in the Territory. Notwithstanding anything else contained herein, upon
receipt by Spectrum of any payment from a sublicensee upon the achievement of
any applicable milestone (a "SUBLICENSEE MILESTONE"), (i) if the Sublicensee
Milestone is also a milestone described in Section 4.3 or 4.4, Spectrum shall
make the applicable milestone payment under Section 4.3 or 4.4 to Chicago Labs
and (ii) the payment received by Spectrum from such sublicensee shall be treated
as sublicense income and subject to the first sentence of this Section 4.5.7;
provided that Spectrum may deduct any payment made pursuant to clause (i) of
this from such sublicense income before calculating the percentage owed to
Chicago Labs pursuant to this Section 4.5.7 in determining Spectrum's obligation
under this Section. Spectrum may only deduct from such sublicense income, under
clause (ii) of this Section, the amount actually paid by Spectrum to Chicago
Labs pursuant to clause (i) of this Section. If Spectrum receives as
Sublicensing Revenues anything of value in lieu of cash payments, Spectrum shall
pay Chicago Labs royalties at the applicable rate under Section 4.5.1, 4.5.2, or
4.5.3 as applicable, above based on the fair market value of such payment,
unless Chicago Labs waives in writing such payment obligation.

United States designated in writing by Chicago Labs from time to time. In the
case of sales outside the United States, the rate of exchange to be used in
computing the amount of currency equivalent in U. S. Dollars due Chicago Labs
shall be made at the rate of exchange utilized by Spectrum in its worldwide
accounting system under GAAP.

             4.5.9 Income Tax Withholding. If laws, rules or regulations require
withholding of income taxes or other rates imposed upon payments set forth in
this Section 4, Spectrum may make such withholding payments as required and
subtract such withholding payments from the payments set forth in this Section
4. Spectrum shall submit appropriate proof of payment of the withholding rates
to Chicago Labs within a reasonable period of time. Spectrum shall use efforts
consistent with its usual business practices to ensure that any withholding
taxes imposed are reduced as far as possible under the provisions of the current
or any future double taxation treaties or agreements between foreign countries,
and the Parties shall cooperate with each other with respect thereto, with the
appropriate Party under the circumstances providing the documentation required
under such treaty or agreement to claim benefits thereunder.

time as each royalty payment is made by Spectrum, a written report of Net Sales
of the Products on a Product by Product and country by country basis and the
royalty due and payable thereon, for the *** period upon which the royalty
payment is based. Net Sales made in currencies other than U.S. Dollars will be
translated into U.S. Dollars as provided in Section 4.5.8 and added to Net Sales
made in U.S. Dollars for purposes of determining aggregate Net Sales and the
royalties due to Chicago Labs.

         4.6 RECORDS. Spectrum shall keep full, complete and proper records and
accounts of all sales of Products by Spectrum, its Affiliates, and to the extent
it acquires rights to do so, its sublicensees and distributors, in accordance
with GAAP, in sufficient detail and in the currencies in which the sale was made
to enable the royalties payable on each Product to be determined. All such
records, statements, reports and accounts referred to in this Section 4.6 shall
be retained for a period of *** after the end of the period to which they apply.

         4.7 AUDIT

calculation of royalties arising under this Agreement. After this inspection, if
Chicago Labs still disagrees with the report provided by Spectrum, with

business hours, to appoint independent auditors reasonably acceptable to
Spectrum and have them during normal business hours, inspect and copy the books
and accounts of Spectrum or its Affiliates, related to the payment and
calculation of royalties arising under this Agreement. Spectrum shall cooperate
and cause Spectrum's Affiliates, to cooperate with such auditors. The auditors
performing the audit shall disclose to Chicago Labs only information relating to
the accuracy of records kept and the payments made, and shall be under a duty to
keep confidential any other information obtained from such records. Spectrum
shall audit the books and accounts of its sublicensees and/or distributors, if
any, using its independent auditor or a comparable reputable auditor. Spectrum
shall share the results of its audit with Chicago Labs.

             4.7.2 If any such audit establishes that Spectrum has underpaid or
overpaid the amount due, Spectrum shall promptly pay any remaining amounts due
as established by such audit or Chicago Labs shall promptly refund any over
payment. If the underpayment is by *** percent (***%) or more during any
calendar year, Spectrum shall reimburse Chicago Labs for its out-of-pocket
expense of such audit with interest at the rate specified in Section 4.8 below
for late payments on any such overdue payment from the date due until paid.

         4.8 LATE PAYMENTS. Any payments or reimbursements due Chicago Labs
under this Agreement that are not paid on the due date shall accrue interest at
the lower of the rate of *** percent (***%) per annum, or the maximum rate
allowed by law, from the due date until paid in full.

         4.9 NO REFUNDS. No payments or reimbursements once received by Chicago
Labs pursuant to Sections 4.1 through 4.4 above are refundable in whole or in
part.

Licensed Field to make, have made, use, sell, have sold, import, export and
license all Improvements that are owned by Chicago Labs and all Joint Inventions
for so long as Spectrum is prosecuting and maintaining the Patents contained in
such Joint Inventions. Chicago Labs shall, and hereby does, grant Spectrum a
perpetual, royalty-free license to use all Improvements owned by Chicago Labs
and all information, know-how and other data pertaining to all Improvements and
the Joint Inventions after Spectrum's royalty obligations under Section 4.5 have
expired or been terminated by Spectrum due to a breach of this Agreement by

consult with Chicago Labs with regard to the preparation, filing, prosecution
and/or maintenance of the Patents within the Chicago Labs Patent Rights and
Joint Patents and the scope of claims contained therein. Notwithstanding the

granted under this Agreement unless Spectrum later elects, with the consent of
Chicago Labs, to continue and maintain such patent or patent application, in
which case the patent or patent application shall remain within the Chicago Labs
Patent Rights and licenses hereunder. Spectrum shall give Chicago Labs at least
*** prior written notice of its election to discontinue or abandon any such
patent or patent application within the Chicago Labs Patent Rights during which
time Chicago Labs may elect, in its sole discretion, to prosecute, file,
continue and maintain such patent or patent application at its sole cost and
expense and for its sole benefit by delivery of written notice to Spectrum. If
Chicago Labs does not notify Spectrum in writing during such *** period that it
is exercising such rights, the patent or patent application shall be deemed
abandoned and neither Chicago Labs nor Spectrum shall have any further
responsibility for any such abandoned patent applications or patents.

         5.3 PROSECUTION AND MAINTENANCE OF PATENTS FOR JOINT INVENTIONS.
Spectrum shall file, prosecute and maintain Patents for any Joint Inventions.
The costs and expenses of such Joint Inventions shall be borne by ***. If
Spectrum no longer desires to retain responsibility for such Joint Invention or
for such Joint Invention in a particular country, Spectrum will provide at least

not the obligation, to assume such responsibility at its sole cost and expense.
If Chicago Labs agrees to assume such responsibility and expense, Spectrum shall
retain all of its right, title and interest in such Joint Invention, and any
Patents claiming the same. ***

"Licensee" under that Article, and (ii) in all other cases, Spectrum shall have
the first right, but not the obligation, to file suit or take other action to
prevent such infringements of any such Patents. To the extent Spectrum takes
such action, Spectrum shall control any such action and may enter into
settlements, stipulated judgments or other arrangements respecting such
infringement, at its own expense; provided, however, that such proposed
settlements, judgments or arrangements shall be subject to Chicago Labs'
consent, not to be unreasonably withheld. In the event that Spectrum takes such
action, Spectrum shall indemnify, defend and hold Chicago Labs harmless from any
costs, expenses and liabilities respecting the action for such claimed
infringement. Chicago Labs shall permit an action to be brought by Spectrum in
Chicago Labs' name if required by law. Chicago Labs agrees to provide all

                (C) Spectrum shall promptly notify Chicago Labs in writing of

expenses or liability respecting all such action, and (iii) retain any and all

Affiliates or sublicensees any claim of infringement of a Patent right based
upon the use of, or arising as a result of the exercise of the rights and
licenses granted hereunder to the Chicago Labs Technology (each an "ALLEGED
INFRINGEMENT"), Spectrum shall have the right to respond to and defend any and

expense, to retain counsel of its choice to represent it in any such defense
action.

provide a copy of (i) any claim of Alleged Infringement filed with a court or
governmental authority or (ii) any written notice of an Alleged Infringement
from an attorney or law firm. Within a reasonable period of time in advance of
any responsive deadline required by law or otherwise set forth in the claim or
notice of Alleged Infringement, Spectrum shall notify Chicago Labs in writing as
to whether or not Spectrum intends to respond to such Alleged Infringement. In
the event that Spectrum does not intend to respond to any such claim or notice
or, notwithstanding Section 5.4.2(a), if Spectrum, in its sole discretion, asks
Chicago Labs to respond to any such claim or notice, Chicago Labs shall have the
right, in its sole discretion, to respond to and litigate or settle such Alleged
Infringement, in which case Chicago Labs shall pay any and all future costs and
expenses incurred by Spectrum in such action, and shall indemnify, defend and
hold Spectrum harmless from any future costs, expenses or liability respecting

Section 3.3 of this Agreement or suggesting that any other person has any claim
of legal or beneficial ownership with respect thereto, and there is no
agreement, decree, arbitral award or other provision or contingency which
obligates Chicago Labs to grant licenses in the Chicago Labs Technology.

         EXCEPT AS PROVIDED IN SECTION 8.1, CHICAGO LABS MAKES NO
REPRESENTATIONS OR WARRANTIES CONCERNING THE CHICAGO LABS TECHNOLOGY, INCLUDING
WITHOUT LIMITATION, ANY EXPRESS OR IMPLIED WARRANTY CONCERNING THE
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OF THE CHICAGO LABS
TECHNOLOGY.

9. ADDITIONAL COVENANTS.

         9.1 PRESERVATION OF TITLE AND RIGHTS. Chicago Labs shall retain
ownership and title to all Chicago Labs Technology owned by Chicago Labs and
licensed hereunder and shall use diligent efforts at least equivalent to those
Chicago Labs uses for its other technology of like kind to preserve and maintain
such ownership and title, subject to Spectrum fully performing all of its
obligations under this Agreement. Chicago Labs shall use diligent efforts at
least equivalent to those Chicago Labs uses for its other technology of like
kind to maintain in full force and effect all Third Party licenses to which
Chicago Labs is a party and under which Chicago Labs licenses rights to
Spectrum, subject to Spectrum fully performing all of its obligations under this
Agreement.

         9.2 NO CONFLICTS. Neither Party shall grant any right, license or
interest in or to the Chicago Labs Technology, or any portion thereof,
inconsistent with the rights granted to Spectrum herein. Without the other
Party's prior written consent, neither Party shall enter into any agreement that
creates additional obligations upon the other Party or, except to the extent
otherwise permitted in this Agreement, limits the exercise of the other Party's
rights hereunder or diminishes the other Party's rights hereunder.

         9.3 UNIVERSITY LICENSE AGREEMENT. Chicago Labs shall be responsible for
and pay all costs that may become due under the University License Agreement or
any other Third Party license agreement as a result of the transactions and
activities contemplated by this Agreement, including but not limited to license
fees, milestone payments and royalty payments required thereunder. Chicago Labs
shall not, without the prior written consent of Spectrum, (i) terminate the
University License Agreement or (ii) amend the University License Agreement or
exercise or waive any rights under the University License Agreement in a manner
that would diminish the rights granted to Spectrum hereunder, impose any
additional obligations on Spectrum or otherwise be detrimental to Spectrum.
Chicago Labs shall not take


                                       23




any actions or make any omissions that would be likely to or do in fact
constitute or cause a material breach of the University License Agreement, such
that the licensor thereunder would be entitled to terminate such agreement or
amend or modify it in any way that would adversely affect a license or other
rights granted to Spectrum under this Agreement. Notwithstanding the foregoing,
Chicago Labs shall not be liable under this Section for its breach of a term of
the University License Agreement, if the primary cause of Chicago Labs breach of
the term of the University License Agreement is due to a breach by Spectrum of
the same obligation under this Agreement. Chicago Labs acknowledges that
Spectrum shall have the right, in accordance with the terms set forth in the
Amendment to the University License Agreement, a certified true copy of which
Chicago Labs shall deliver to Spectrum promptly after its execution, to be
assigned and assume the University License Agreement in the event Chicago Labs
is in default under the University License Agreement and agrees that it shall
not have any cause of action against Spectrum solely for taking assignment to
and assuming such University License Agreement.

         9.4 EXECUTION OF DOCUMENTS. In order to achieve the intent of Section
5.2, 5.3 and 11. 5(b), each Party shall promptly execute or have executed by its
employees, agents and consultants all documents necessary to vest ownership of
inventions and related intellectual property rights relating to Joint Patents in
Chicago Labs and Spectrum as provided in Section 5.3, to enable Spectrum to
file, prosecute and maintain the Patents within the Chicago Labs Patent Rights
and Joint Patents as provided in Sections 5.2 and 5.3, the Parties' back-up
right pursuant to Section 5.2, and to transfer to Chicago Labs the benefit of
Spectrum's research and development work under Section 11.5(b). If Spectrum is
unable, after reasonable effort, to secure the signature of any Chicago Labs'
employee, agent or independent contractor on any document needed to apply for,
prosecute or defend any patent or other intellectual property right or
protection relating to the Chicago Labs Patent Rights or the Joint Patents,
Chicago Labs hereby designates and appoints Spectrum and its duly authorized
officers and agents as its agent and attorney in fact to execute, verify and
file applications, and to do all other lawfully permitted acts necessary to
protect Spectrum's rights in Joint Patents and to enable Spectrum to file,
prosecute and maintain Chicago Labs Patent Rights and Joint Patents with the
same legal force and effect as if executed by Chicago Labs. If Chicago Labs is
unable, after reasonable effort, to secure the signature of any Spectrum
employee, agent or independent contractor on any document needed to apply for,
prosecute or defend any patent or other intellectual property right or
protection relating to Joint Patents or to transfer to Chicago Labs the benefit
of Spectrum's research and development work, Spectrum hereby designates and
appoints Chicago Labs and its duly authorized officers and agents as its agent
and attorney as its attorney in fact to execute, verify and file applications,
and to do all other lawfully permitted acts necessary to protect Chicago Lab's
rights in Joint Patents and such research and development work with the same
legal force and effect as if executed by Spectrum.

10. CONFIDENTIALITY AND PUBLICATION.

             10.1 TREATMENT OF CONFIDENTIAL INFORMATION. The Parties agree that
during the term of this Agreement, and for a period of seven (7) years after
this Agreement terminates or expires, a Party receiving Confidential Information
of the other Party will (i) maintain in confidence such Confidential Information
to the same extent such Party maintains the confidentiality of its own
Confidential Information, (ii) not disclose such Confidential Information to any
Third Party without the prior written consent of the disclosing Party and (iii)
not use such Confidential Information for any purpose other than the exercise of
a Party's rights or performance of a Party's obligations under this Agreement;
provided however, that the provisions of this Section 10.1 shall not prevent a
Party from disclosing Confidential Information if such disclosure:

                (A) is made to its employees, directors, accountants, attorneys,
contractors or consultants who reasonably require such disclosure on a need to
know basis and who are bound to it by obligations of confidentiality and non-use
no less stringent than the obligations between Spectrum and Chicago Labs
hereunder;

                (B) is made to collaborators for the purpose of performing the
obligations or exercising the rights of a Party hereunder and who are bound to
that Party by obligations of confidentiality and non-use no less stringent than
the obligations between Spectrum and Chicago Labs hereunder;

                (C) is in response to a valid order of an United States court or
otherwise required by law or regulation, provided however that receiving Party
shall first have given notice to the disclosing Party and shall have made a
reasonable effort to obtain a protective order by: (i) seeking protection of
Confidential Information not relevant to the court's inquiry from a general
disclosure (e.g., without limitation, requesting limited and in-camera review by
such court and/or seeking that such information be treated under seal); (ii)
seeking to redact any Confidential Information; and (iii) in any event requiring
that, to the extent ordered to be disclosed, that such disclosure of
Confidential Information be used only for the purposes for which the order was
issued; or

                (D) is necessary to: (i) file or prosecute Patents in accordance
with this Agreement; (ii) submit regulatory filings with respect to Products in
accordance with this Agreement; (iii) prosecute or defend litigation; (iv) make
required governmental securities filings and other such similar and required
disclosures by law, subject to appropriate redactions and requests for
confidential treatment as permitted by law; (v) make disclosures required by the
principal stock exchange on which the Party's stock is traded, subject to
appropriate redactions and requests for confidential treatment as permitted by
law and the rules of such exchange; (vi) conduct pre-clinical or clinical trials
of Products in accordance with this Agreement, provided any Affiliates or Third
Parties conducting pre-clinical trials agree to be bound by terms of


                                       25




confidentiality and non-use at least equivalent in scope to those set forth in
this Section 10.1 and any Affiliates or Third Parties conducting clinical trials
agree to be bound by terms of confidentiality and non-use that are customarily
obtained in connection with such clinical trials; or (viii) enable Affiliates or
bona fide potential or actual sublicensees to evaluate and/or exercise their
rights under a sublicense that would be or has been issued in accordance with
this Agreement, provided such Affiliates and Third Parties agree to be bound by
similar terms of confidentiality and non-use at least equivalent in scope to
those set forth in this Section 10.1.

         10.2 PUBLIC STATEMENTS.

             10.2.1 Publications. Chicago Labs or Spectrum, as the case may be,
may publish or present information derived from the performance of this
Agreement, provided that: the publishing Party first provides the non-publishing
Party with a copy of the proposed publication or presentation for comment and
input at least forty-five (45) days prior to any submission for publication or
presentation and if any such information was derived from the non-publishing
Party's efforts under this Agreement, the non-publishing Party shall have the
right to require the publishing Party to redact such information from the
proposed publication. In addition, at the non-publishing Party's request, the
publishing party will further delay the presentation or publication for an
additional forty-five (45) days so as to allow the non-publishing party time to
file for patent protection or other intellectual property protection. If a
publication by Spectrum results from work relating to the Chicago Labs
Technology, Spectrum agrees to acknowledge Chicago Labs and give credit to
Chicago Labs' scientists, as scientifically appropriate, based on any
contribution they may have made to the work. Likewise, if a publication by
Chicago Labs results from work performed by Spectrum, Chicago Labs agrees to
acknowledge Spectrum and give credit to Spectrum' scientists, as scientifically
appropriate, based on any contribution they may have made to the work.

             10.2.2 Other Public Statements. Except as provided in Section
10.2.1, or as otherwise required by law or the rules of the principal stock
exchange on which the Party's stock is traded, no Party shall originate any
public statement, news release or other written public announcement, whether in
the public press, stockholders' reports, or otherwise, relating to this
Agreement or to any sublicense hereunder, or to the performance hereunder or any
such agreements, or use a Party's name for any purpose, including, without
limitation, in connection with the advertising or sale of Products, without the
prior written approval of the other Party, such consent not to be unreasonably
withheld. The Parties each agree to respond to each such request within five (5)
business days of receipt of a request (unless a shorter period of time is
necessary to comply with law). Notwithstanding anything to the contrary in this
Agreement, each party shall be permitted to publicly disclose (i) the existence
of this Agreement, (ii) that Chicago Labs and Spectrum are the parties to this
Agreement, and (iii) the Chicago Labs Technology covered by this Agreement. In
the case of unintentional public disclosure concerning this Agreement, any
Product or any other subject matter hereof, the disclosing Party shall promptly
inform the other Party of such disclosure and the other Party shall be entitled
to make a public announcement


                                       26




regarding the subject matter of the disclosure. The other Party shall notify the
disclosing Party of their intention to make such an announcement. Following a
Party's consent to or approval of the public announcement of any information
pursuant to this Section 10.2.2, both Parties shall be entitled to make
subsequent public announcements of such information without renewed compliance
with this Section 10.2.2, unless the scope and/or duration of such consent or
approval is expressly limited. Upon conclusion of this Agreement, the Parties
will publish a press release on their future cooperation.

11. TERM, DEFAULT AND TERMINATION.

         11.1 TERM OF AGREEMENT. The term of this Agreement shall commence on
the Effective Date. Unless terminated early in accordance with the provisions of
this Agreement, the term of this Agreement shall endure on a Product-by-Product
and country-by-country basis until the expiration of the obligation to pay
royalties under Section 4.5 above applicable to such Product in such country.
This Agreement shall expire in its entirety after the date that Spectrum no
longer owes any royalties to Chicago Labs under Section 4.5. Spectrum
acknowledges that the University License Agreement and hence Spectrum's rights
under the Chicago Labs Patent Rights (to the extent they relate to the patents
licensed by the University to Chicago Labs) terminate upon the last to expire of
the patents licensed to Chicago Labs under the University License Agreement,
unless sooner terminated under Section 12.1 of the University License Agreement.

         11.2 UNILATERAL TERMINATION - SPECTRUM. Spectrum shall have the
unilateral right to terminate this Agreement, in its entirety or on a
Product-by-Product or country-by-country basis, at any time for any reason upon
prior written notice to Chicago Labs given at least *** prior to the desired
date of termination.

         11.3 UNILATERAL TERMINATION - CHICAGO LABS. Spectrum shall file the
first IND, or its equivalent, with the FDA, or a similar agency in another
jurisdiction, for a Product no later than *** and will file an NDA for such
Product within *** after filing the related IND. Chicago Labs shall agree to
reasonable extensions of the foregoing deadlines on request by Spectrum provided
that Spectrum demonstrates good faith efforts to meet the deadline for which an
extension is requested. The parties acknowledge that the intention of this
Section 11.3 is to allow Chicago Labs meet its obligations under the University
License Agreement, and therefore if the University agrees at Chicago Lab's
request to extend the dates for filing an IND and an NDA pursuant to the terms
of the University License Agreement to give Spectrum additional time based on
its previous commercially reasonable, good faith efforts to meet the

Securities and Exchange Commission. Confidential treatment has been requested
with respect to the omitted portions.


                                       27


dates for which an extension is requested or such filing dates are automatically
extended pursuant to the terms of the University License Agreement, then the
dates in this Section shall be extended an equal time period or in the case of
an automatic extension pursuant to the terms of the University License
Agreement, the dates in this Section shall be extended to such dates minus ***.

         11.4 DEFAULT.

             11.4.1 The following event shall constitute an "EVENT OF DEFAULT"
hereunder: a material breach of a material provision of this Agreement by a
Party. For purposes of this Agreement, it is not a "material breach" of this
Agreement by Spectrum if the development of a Product is delayed due to the
following: (i) scientific, medical or technical reasons; (ii) circumstances that
are beyond the control of Spectrum; or (iii) the fault of Chicago Labs. In
addition to the foregoing, termination of the University License Agreement due
to the fault of Chicago Labs or the assignment to and assumption by Spectrum of
the University License Agreement due to a default by Chicago Labs shall
constitute an "Event of Default" under this Agreement with respect to Chicago
Labs.

             11.4.2 Upon the occurrence of any Event of Default by a Party, the
non-defaulting Party may deliver to the defaulting Party written notice of
intent to terminate specifying in reasonable detail the nature of such breach,
such termination to be effective *** after the date set forth in such notice if
the defaulting Party fails to cure such material breach within such *** period.

             11.4.3 If Spectrum fails to pay any license fee, royalty,
installment, patent expenses or other payment required by this Agreement on
time, and such payment remains unpaid for more than ***, Chicago Labs shall have
the right to terminate this Agreement on *** written notice specifying the
failure, unless Spectrum shall pay Chicago Labs within the *** period, all
amounts and interest then due and payable. Upon expiration of the *** period, if
Spectrum has not made all such payments, the rights, privileges and license
granted hereunder shall terminate, unless Spectrum's failure to pay arises from
a bona fide dispute concerning royalties due, in which case either of the
parties may elect to pursue the alternative remedy in Article 12.

             11.4.4 The termination rights under Sections 11.4.2 and 11.4.3
above shall be in addition to and not in substitution for any other remedies
that may be available to the non-defaulting Party. Termination pursuant to such
sections shall not be treated as an election of remedies and shall not relieve
the defaulting Party from liability and damages to the other Party for breach of
this

Securities and Exchange Commission. Confidential treatment has been requested
with respect to the omitted portions.


                                       28




Agreement. Waiver by either Party of a single breach or a succession of breaches
shall not deprive such Party of any right to terminate this Agreement arising by
reason of any subsequent breach.

             11.4.5 In addition to the termination rights provided for in this
Article 11, each Party shall have the right to terminate this Agreement,
immediately by giving written notice of termination to the other Party, if the
other Party files a voluntary petition, or if an involuntary petition is granted
in respect of the other Party and appeal proceedings are not commenced within a
period of *** from the date of such petition under the bankruptcy provisions of
applicable law, or the other Party is declared insolvent, undergoes voluntary or
involuntary dissolution, or makes an assignment for the benefit of its
creditors, or fails or is unable to pay its debts as they come due, or suffers
the appointment of a receiver or trustee over all, or substantially all, of its
assets or properties.

         11.5 EFFECTS OF EXPIRATION OR TERMINATION.

                (A) Rights Upon Expiration. Following the expiration of the term
of this Agreement under Section 11.1, excluding any early termination prior to
expiration, Spectrum shall have and retain a perpetual and fully paid up license
under the applicable Product Licenses. Notwithstanding the foregoing, Spectrum
shall retain all rights and interest in all materials, inventions, discoveries
and know-how (whether or not patentable or patented) solely generated by
Spectrum in the course of performing research and development activities under
the licenses granted in this Agreement. Other than rights intended to survive
expiration, or as otherwise provided under Section 11.5(e), neither Party shall
have any further rights or obligations upon the expiration of this Agreement.

                (B) Rights Upon termination by Chicago Labs under Sections 11.3
or 11.4 or by Spectrum under Section 11.2. Upon any termination of this
Agreement by Chicago Labs under Section 11.3 or 11.4 or by Spectrum under
Section 11.2 occurring prior to the regularly scheduled expiration date of this
Agreement, (i) all rights and licenses granted by Chicago Labs to Spectrum shall
terminate and revert to Chicago Labs and (ii) Spectrum shall return to Chicago
Labs or destroy at Chicago Labs' option the Chicago Labs Materials. The
foregoing provisions shall also apply to the partial termination of this
Agreement by Spectrum on a Product-by-Product basis in accordance with Section
11.2, provided, however, that in such event: (1) only those rights that solely
pertain to the Product and/or country being terminated would revert back to
Chicago Labs; (2) only those Chicago Labs Materials that solely pertain to the
Product and/or country being terminated would be returned or destroyed by
Spectrum. In addition Spectrum shall at no cost to Chicago Labs transfer to
Chicago Labs the benefit of all research and development work it has performed
or had performed on Products. At the

same time, Spectrum shall provide to Chicago Labs at no cost to Chicago Labs all
CMC data, preclinical testing and stability data and results and clinical trial
data and results relating to the development of Products and a technology
transfer package for all processes, formulations, and protocols for the
manufacture of APIs for Products and for finished Products, If Spectrum has
licensed any technology from Third Parties relating to the Chicago Labs
Technology or any Product, Spectrum shall use commercially reasonable efforts to
obtain the rights to transfer and to transfer such rights to Chicago Labs at no
cost to Chicago Labs. Notwithstanding the foregoing, Spectrum shall retain its
right, title and interest under Section 5.1 in any Improvements made solely by
Spectrum and in any Joint Inventions, but shall grant to Chicago Labs a
nonexclusive, sublicensable, royalty free license to such Improvements to the
extent that the development, making, having made, use, offer for sale,
distribution, importation, or exportation of Products in the License Field by
Chicago Labs, its Affiliates or licensees would, but for the license, violate
Spectrum's patent rights.

                (C) Rights Upon termination by Spectrum under Section 11.4. Upon
any termination of this Agreement by Spectrum under Section 11.4 occurring prior
to the regularly scheduled expiration date of this Agreement, the license rights
granted by Chicago Labs to Spectrum contained in this Agreement shall continue
in full force and effect, however, Spectrum's obligations under this Agreement
shall terminate. Notwithstanding the foregoing, Chicago Labs shall retain its
right, title and interest under Section 5.1 in any Joint Inventions

                (D) Payments. Not later than *** after the expiration or
termination date of this Agreement, each Party shall pay to the other Party any
amounts that are then due and payable, including but not limited to any final
period royalty report and payment. Notwithstanding anything in this Agreement to
the contrary, Spectrum shall not be required to pay any remaining monthly
installments yet to be paid pursuant to Sections 4.2 or 4.3 above, if this
Agreement is terminated prior to the payments of all installments pursuant to
Sections 4.2 or 4.3.

                (E) Accrued Rights; Surviving Obligations. Termination or
expiration of this Agreement for any reason shall be without prejudice to any
rights which shall have accrued to the benefit of either Party prior to such
termination or expiration, and shall not relieve either Party from its
obligations which are expressly indicated to survive expiration or termination
of this Agreement, including, without limitation, those under Articles 7, 10, 12
and 13 and Sections 4.6 through 4.9, 5.1 through 5.4, 11.5 and 11.6 shall
survive any expiration or termination of this Agreement.

         11.6 WORK-IN-PROGRESS. Notwithstanding anything in this Agreement to
the contrary, upon any such early termination of the license granted hereunder
in accordance with this Agreement, Spectrum shall be entitled to finish any
work-in-progress and to sell any completed inventory of a Product which remain
on hand as of the date of the termination, so long as Spectrum pays to Chicago
Labs the royalties applicable to said subsequent sales in accordance with the
terms and conditions as set forth in this Agreement, provided that no such sales
shall be permitted after the expiration of *** after the date of termination.

12. DISPUTE RESOLUTION.

         12.1 ARBITRATION. Any claim, dispute, or controversy of any nature
arising out of or relating to this Agreement, including, without limitation, any
action or claim based on tort, contract or statute, or concerning the
interpretation, effect, termination, validity, performance and/or breach of this
Agreement (each, a "Dispute") between the Parties shall be finally settled by
binding arbitration conducted in the English language in accordance with the
Rules of Commercial Arbitration of the American Arbitration Association ("AAA").
The arbitration shall be held in Cook County, Illinois, and shall be conducted
by three (3) arbitrators who are knowledgeable in the subject matter at issue in
the dispute. One (1) arbitrator will be selected by Chicago Labs, one (1)
arbitrator will be selected by Spectrum, and the third arbitrator will be
selected by mutual agreement of the two (2) arbitrators selected by the Parties,
provided that if a Party fails to select an arbitrator within thirty (30) days
of the request for arbitration, the arbitrator that was to be selected by such
Party shall be appointed in accordance with the rules of the AAA. During the
period prior to the hearing, each Party shall have the right to conduct up to
two (2) depositions and to submit up to twenty (20) document requests to the
other Party. The arbitrators may proceed to an award, notwithstanding the
failure of either Party to participate in the proceedings. The arbitrators
shall, within forty-five (45) calendar days after the conclusion of the
arbitration hearing, issue a written award and statement of decision describing
the essential findings and conclusions on which the award is based, including
the calculation of any damages awarded. The arbitrators shall be authorized to
award compensatory damages, but shall NOT be authorized to (i) award
non-economic or punitive damages (except to the extent expressly permitted by
this Agreement), or (ii) reform, modify or materially change this Agreement or
any other agreements contemplated hereunder; provided, however, that the damage
limitations described in part (i) of this sentence will not apply if such
damages are statutorily imposed. The arbitrators also shall be authorized to
grant any temporary, preliminary or permanent equitable remedy or relief that
the arbitrators deem just and equitable and within the scope of this Agreement,
including, without limitation, an injunction or order for specific performance.
The award of the arbitrators shall be the sole and exclusive remedy of the
Parties. Judgment on the award rendered by the arbitrators

may be enforced in any court having competent jurisdiction thereof, subject only
to revocation on grounds of fraud or clear bias on the part of the arbitrators.
Notwithstanding anything contained in this Section 12.1 to the contrary, each
Party shall have the right to institute judicial proceedings against the other
Party or anyone acting by, through or under such other Party, in order to
enforce the instituting Party's rights hereunder through specific performance,
injunction or similar equitable relief.

         12.2 ADMINISTRATION. Each Party shall bear its own attorneys' fees,
costs, and disbursements arising out of the arbitration, and shall pay an equal
share of the fees and costs of the arbitrators; provided, however, that the
arbitrators shall be authorized to determine whether a Party is the prevailing
party, and if so, to award to that prevailing party reimbursement for its
reasonable attorneys' fees, costs and disbursements (including, for example,
expert witness fees and expenses, photocopy charges and travel expenses), and/or
the fees and costs of the arbitrators. Absent the filing of an application to
correct or vacate the arbitration award (if permitted by AAA rules), each Party
shall fully perform and satisfy the arbitration award within fifteen (15) days
of the service of the award.

         12.3 WAIVERS. By agreeing to the binding arbitration provision in
Section 12.1, the Parties understand that they are waiving certain rights and
protections which may otherwise be available if a Dispute between the Parties
were determined by litigation in court, including, without limitation, the right
to seek or obtain certain types of damages precluded by this provision, the
right to a jury trial, certain rights of appeal, and a right to invoke formal
rules of procedure and evidence.

         12.4 NON-ARBITRABLE DISPUTES. Section 12.1 shall not apply to any
dispute, controversy or claim that concerns (A) the validity, enforceability or
infringement of a Patent, trademark or copyright; or (B) any antitrust,
anti-monopoly or competition law or regulation, whether or not statutory. All
such disputes, controversies or claims, and all judicial actions brought in
order to enforce the instituting Party's rights hereunder through specific
performance, injunction or similar equitable relief, shall be brought only in
the state or federal courts sitting in Cook County, Illinois. The Parties hereby
submit to the exclusive jurisdiction of such courts.

13. GENERAL PROVISIONS.

         13.1 FURTHER ASSURANCES. At any time or from time to time on and after
the Effective Date, each Party, at the request of the other Party, shall (i)
deliver to the other Party such records, data or other documents consistent with
the provisions of this Agreement, (ii) execute, and deliver or cause to be
delivered, all such assignments, consents, documents or further instruments of
transfer or license, and (iii) take or cause to be taken all such other actions,
as the other Party may reasonably deem necessary or desirable in order for such
other Party to obtain the full benefits of this Agreement and the transactions
contemplated hereby.

by a written document which is signed by both Parties.

         13.4 FORCE MAJEURE. Neither Party shall be liable for any delay or
failure of performance (other than payment obligations) to the extent such delay
or failure is caused by circumstances beyond its reasonable control and that by
the exercise of due diligence it is unable to prevent, provided that the Party
claiming excuse uses its commercially reasonable efforts to overcome the same.

         13.5 LIMITATION OF LIABILITY. EXCEPT FOR LIABILITY FOR BREACH OF
CONFIDENTIALITY OR FOR INFRINGEMENT OR MISAPPROPRIATION, NEITHER PARTY SHALL BE
LIABLE TO THE OTHER FOR INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL OR
EXEMPLARY DAMAGES, INCLUDING BUT NOT LIMITED TO LOST PROFITS (EXCEPT, HOWEVER,
ANY LOST PROFITS OF SPECTRUM AS THE RESULT OF ANY BREACH BY CHICAGO LABS OF ANY

         13.6 ASSIGNMENT. Except for sublicensing rights as set forth in Section

non-assigning Party except, to a successor in interest pursuant to a merger,
acquisition or sale of all or substantially all of the assignor's assets to
which this Agreement relates. Subject to the limitations on assignment herein,
this Agreement shall be binding upon and inure to the benefit of any successors
in interest and permitted assigns of Chicago Labs and Spectrum. Any such
successor or permitted assignee of Spectrum' interest shall expressly assume in
writing the performance of all terms and conditions of this Agreement to be
performed by Spectrum.

Agreement be held invalid


                                       33



or unenforceable by a court of competent jurisdiction, it shall be considered
severed from this Agreement and shall not serve to invalidate the remaining
provisions thereof. The Parties shall make a good faith effort to replace any
invalid or unenforceable provision with a valid and enforceable one such that
the objectives contemplated by them when entering this Agreement may be
realized.

         13.10 NO WAIVER. Any delay in enforcing a Party's rights under this
Agreement or any waiver as to a particular default or other matter shall not
constitute a waiver of such Party's rights to the future enforcement of its
